ruckus icx 7150-c12p Stuck on previous owners name with “recover.me”

[Mmac88]

Hey all, so I recently bought a lennar home which had previously been lived in.  It had the ruckus switch installed as most do. My issue is that it is configured to the previous owners name. I have my own ISP and router connected but I cannot access the ruckus to remove their old account, or edit their settings. I can’t access the unleashed app or anything. I’ve done multiple hard resets and the only option I have is their old set up or “recove.me-AE600”. 

im not awesome with stuff like this and would really like to get it sorted. 

Appreciate any help.
